United States Patent 6,020,954
Issued February 1, 2000
Method and associated apparatus for the standardized grading of
gemstones
Abstract:
A method and associated apparatus for the standardized grading of
gemstones is provided. The system gauges the spectral response of a
gemstone subject to a plurality of incident light sources within an
imaging apparatus. Light energy data is captured in the form of pixel
data sets via a charge coupled device of the imaging apparatus of the
local station. The analysis station employs a data processor and model
database for assessing the aesthetic and/or monetary value of gemstones
by way of the communicated pixel data sets. Gemstones qualities are
analyzed by the plurality of light sources of the imaging apparatus and
quantified relative to model pixel data sets of the database and
recorded for future reference therein.
